Abstract-Demosaicking is an estimation process to determine missing color values when a single-sensor digital camera is used for color image capture. In this paper, we propose a number of new methods based on the application of Taylor series and cubic spline interpolation for color filter array demosaicking. To avoid the blurring of an edge, interpolants are first estimated in four opposite directions so that no interpolation is carried out across an edge. A weighted median filter, whose filter coefficients are determined by a classifier based on an edge orientation map, is then used to produce an output from the four interpolants to preserve edges. Using the proposed methods, the original color can be faithfully reproduced with minimal amount of color artifacts even at edges.Index Terms-Color filter array, cubic spline, demosaicking, Taylor series, weighted median filter.

This study presents findings from three different disciplines in STEMM (Science, Technology, Engineering, Mathematics and Medicine) and across different models of student-focused teaching. Specifically, we assessed the feasibility and effectiveness of flipped classroom approaches combined with team based learning (TBL), and TBL alone within STEMM, particularly in the disciplines of Physics, Engineering and Medicine across different year levels. TBL activities were incorporated into undergraduate Physics and Engineering cohorts, with students from a diverse range of majors and backgrounds and a graduate level Doctor of Medicine (MD) cohort. Quiz scores from the Physics cohort were significantly improved following TBL, exam scores from the engineering cohort were more evenly distributed than pre-TBL quiz scores and students in the medical cohort had higher quiz scores when working within teams rather than alone. Qualitative survey responses from both the physics and engineering cohorts indicated that students felt TBL was positive and increased their understanding of key concepts. Informal feedback from medical students following TBL classes was also very positive and students demonstrated obvious engagement. Comparisons for pre-versus post-TBL quiz scores for Physics, for pre-TBL quartile versus exam scores in Engineering and for Team versus Individual learning quiz scores in Medicine all provide evidence of effective student engagement and performance. The observation study suggests that TBL is a feasible and effective method of student-focused learning within STEMM. More rigorously designed studies are now required to further explore these findings.

When a single image sensor is used to images, only one colour value is acquired location. Colour filter array (CFA) demosa the estimation of the other two missing c order to produce a full colour image. In this shown that cubic spline interpolation is su demosaicking for producing a smooth colou the known fact that it can generate a smoot set of data points. In our approach to o solution for cubic spline interpolation, the extra conditions were derived based on between colour planes. Our proposed meth( cubic spline interpolation in conjunction A based on edge orientation, has been shown other existing demosaicking methods.
